FOOT-WARM ER.

SPECIFICATION forming part of Letters Patent No. 628,182, dated July 4, 1899. Application filed 0ctoher12, 1898. Serial No. 693,327. (No model.)

To all whom it may concern..-

Be it known that we, AUGUST MEYER and WVILLIAM O. MEYER, citizens of the United States, residing at Addieville, in the county of Washington and State of Illinois, have invented certain new and useful Improvements in Foot-VVarmers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

Ourinvention has relation to improvements in foot-warmers; and it Consists in the novel arrangement and combination of parts more fully set forth in the specification and pointed out in the claims.

In the drawings, Figure l is a top plan of the device, the supporting-grating on one side being broken away to show the interior register. Fig. 2 is a horizontal section online 2 2 of Fig. 3. Fig. 3 is a front elevation of the device. Fig. 4 is a longitudinal vertical section on line 4 4 of Fig. 1. Fig. 5 is a trans verse section on line 5 5 of Fig. 4. Fig. 6 is a detail longitudinal section of the burnersupport. Fig. 7 is a longitudinal sectional detail of the oil-tank and air-chamber confined within the same; and Fig. 8 is an end view of the frame proper, showing the hand-hole in the vertical wall at that end, (there being a corresponding hand-hole at the opposite end,) the oil-tank being omitted from this view.

The object of ourinventionis to construct a foot-warming stove in which the fuel used is a liquid hydrocarbonsuch as gasolene,- kerosene, petroleum, or the like-special attention being had to the mechanism for effecting the even distribution of the heated aircurrents and products of combustion, to the location of the burners, to the mechanism for feeding and delivering the fuel to the latter, and to other details of construction whose purpose and function will be better apparent from a detailed description of the invention, which is as follows:

Referring to the drawings, 1 represents an open ornamental frame resting'on legs 2, the frame supporting at its middle an oil-tank 3, preferably cylindrical in shape, the tank being held securely in the depressions formed in the frame for its reception by straps 4, embracing the opposite ends of the cylinder and 10, passes through the wall of the frame.

secured to the frame. Protecting the oil-tank along the under surface is a shield 5, the latter being removed from the tank sufficiently to leave an air space or chamber 6, through which air is free to circulate, finding ingress and egress throughopenings 7, formed in the opposite vertical walls of the frame. The shield 5 is extended laterally or outwardly on each side in the form of a perforated plate 5, forming the stationary member or section of a register, with the elongated openings 8 of which are adapted to register the corresponding openings of the sliding section or member 9 of said register, the members 9 being coupled by a yoke 10, spanning the shield 5. The shield is secured to the walls of the frame by rivets or in an equivalent manner,tl1e opposite longitudinal edges of the extensions or plates 5 being riveted to the horizontal members 11 of angle strips or plates carried by the frame,

the spaces between the said members 11 and the plates 5 thus forming ways, within which the movable members 9 of the register are adapted to slide. The movable or sliding members of the register are controlled from the outside of the frame byahandle 12, whose shank, which is but an extension of the ygfie e medial portion of the yoke 10 is provided with a fork 13, between the members of which is adapted to be received an arm 14, carried by the movable section of a register 15, the openings 16 of which are adapted to aline with corresponding openings of the detachable bottom 15, which serves as the stationary section or member of said register. Said bottom 15 is secured at the corners to the legs of the frame by screws or otherwise and is provided on each side of the center with hollow depressions or dish-shaped receptacles 17 directly under the burners, as will presently appear. Access to said receptacles is had through hand-holes 18, formed in the end walls of the frame, the holes being adapted" to be closed by pivoted disks or plates 19. The depressions 17 serve to receive a few drops of gasolene or other hydrocarbon which may be ignited, this initially heating the burners to better assist in startinga blaze in the hydrocarbon particles sprayed into the burners, as will more fully hereinafter appear, The sliding member of the register 15 is so mounted that as the upper register 9 is closed the regisregister 15 is opened, and vice versa. The register 15 slides in ways formed by the strips 20, secured along the inner surface of the bottom 15.

Screwed or otherwise driven into the under peripheral wall of the tank 3, at one end thereof, is a pipe-coupling comprisinghollow arms 21 22 22, the arm 21 being the one which leads directlyinto the tank, the shield being cut away to accommodate the screw-t breaded nipple 23, carried by said arm. To the outer ends of the arms 22 22 are coupled the adjacent ends of the teed-pipes 24, which convey the oil to the burners, as will presently appear. At the junction of the arms 21 22 22 and along the outside of the frame is formed a nipple 25, to which is secured the .hollow plug 26, serving as a stufling-box or gland for the stem 27 of a screw-valve of ordinary construct-ion, by which the dew of the oil to the pipes is controlled. The coupling can be cleaned from the outside by unscrewing a plu 2S, screwed into the coupling in alinement with the passage in the arm 21. The upper end of the stem 27 is provided with a hand-wheel 29, the stem passing through a bracket 30, secured to the frame and being provided with a limiting-collar 31 below the arm of the bracket, the collar serving to arrest or. limit the degree to which the valve and stem can be unscrewed. The pipes 24 run along the wall of the frame a suitable distance. Then they are bent inwardly and passed through openings in the frame-wall, the inner deflected portions of the pipes running parallel to the end walls of the frame and occupying a position on each side of the center of the bottom register and approximately to one side of the longitudinal center of the dish-shaped receptacles 17. The ends of the inner deflected portions of the pipes are coupled to the hollow and substantially U-shaped burner-supports 32, the outer arm of each of which is provided with an ordinary needle-valve 33, whose outer polygonal head can be operated by a key 34, inserted through an opening 35, formed in the wall of the frame, (and shown by dotted circles in Fig. 3,) the inner arm of each burner-support serving to support a hollow burner-tube 36, the lower peripheral wall of which is perforated. The pressure above the oil in the tank serves to drive the oil past the needle-valve and inject the hydrocarbon in the form of a fine spray (see Fig. 6) into the hollow burner, the oil taking tire and burning through the openings formed in the walls of said burner. The burners are located directly over the dishshaped receptacles for a purpose already designated.

To insure enough driving pressure for the oil, we provide the tank 3 with an air-chamber 37, held against the front end or head of the tank by a stay-bolt 38, provided at its free end with a tightening-nut 39, which forces the chamber firmly against the head of the tank. The outer end of the chamberis provided with an air-pipe 40, controlled by a valve 41, to the open end of which pipe can be attach d a hose 42, into which may be blown a quantity of air from the lungs, thereby filling the air-tank with a moderate quantity of compressed air, after which the cock 41 is closed and the hose detached. Leading from the upper wall of the air-chamber and passing through and above the tank is a bent pipe 43, whose free open end terminates in the oil-tank just below the surface of the upper peripheral Wall thereof and above the level of the oil to which the tank is normally filled. The oil is tilled from the top after the removal of the screw-cup 44, the height of the oil being indicated by the free end of a wire 45, to which a float 46 is attached. In starting the burners it is apparent that the compressed air with which the air-chamber is tilled will be communicated to the space above the oil through the bent tube 43, forcing the oil to the burners. After the force of the air has been exhausted the vapors generated above the oil by the heat of the flame will perform by their expansive tendency the function performed by the initial pressure of air, so that there will always be enough pressure behind the oil to force the same in the form of spray into the hollow burners. Each burnersupport 32 is provided at a point opposite the needle-valve with a screw-plug 47, which upon removal enables one to clean the interior of the said support.

The present device,though specially termed a foot-warmer, may be employed as a heating-stove for general purposes, such as heatinghall-rooms, bath-rooms, and so on. When it is desired to direct the heat-currents upward,so as to get the full benefit of the burners, then the upper registers are opened, the lower register closing, and when the upper register is closed the heat-currents escape laterally from the frame through the bottom register.

The inner deflected portions of the oil-supply pipes are sufliciently rigid to retain the outer ends of the needle-valves 33 in alinement with the openings 35, through which the keys 34 are inserted for manipulating the same; but as an additional precaution we support the free ends of said pipes by anglebrackets 48, one arm of each bracket being secured to the wall of the frame and the other arm embracing the stem of the needle-Valve immediately below the polygonal head of the same and bearing against the face of the stutling box or gland 49 of said valve.

A foot-warmer, comprising a suitable frame, an oil-tank located centrally therein whereby a foot-rest is formed on either side thereof, suitable burners located within the hollow of the frame, oil-supply pipes leading from the tank to the burners, controllingvalves for the oil, and registers both below and above the burners for regulating the course of the heat-currents, substantially as set forth.
